[NETFILTER]: Add SANE connection tracking helper
This is nf_conntrack_sane, a netfilter connection tracking helper module for the SANE protocol used by the 'saned' daemon to make scanners available via network. The SANE protocol uses separate control & data connections, similar to passive FTP. The helper module is needed to recognize the data connection as RELATED to the control one.
